Matthew Poole and continuators on Ezekiel 43:25

25 Seven dayes shalt thou prepare every day a goat for a sin offering: they shall also prepare a young bullock, and a ram out of the flock without blemish.

By this it appears, that there were seven dayes appointed for consecrating Altar and Priests, and that, either these three Sacrifices were every day of the seven offer'd up, and their blood sprinkled on the Altar, or at least the young Bullock every day, and one Goat, or one Ram with it, the word here is copulative, but possibly the sense disjunctive; for so this particle is often used.
